Application filed may 21, 1912.

Serial No. 698,?13.

To all whom it may concern:

lie it known that- 1, James l dimension, a citizen of the Jnited'Statcs, residing at Kalamazoo, h'lichigan, have invented certain new and useful Improvements in Signs, of which the following is a specification.

This invention relates to improvements in signs.

The main objects of this invention are to provide in a. sign in which the sign indicia or characters are formed of lenses illuminated by lamps, an improved lens by which spot lights are effectively obviated. Further, to provide an improved means for securing the lenses of such structures in which the parts are economically produced and easily and quickly assembled.

Further objects, and objects relating to structural details, will definitely appear from the detailed description tofollow.

l accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly pointed out in the claims.

A structure which is a preferred embodiment oi my invention is clearly illustrated in the accompanying drawing", forming s part of this specification, in which:

l re l is a. detail front view of n defined and structure embodying the oi my invonlion, a single letter only being illustrated, the parts being shown mainly in conventional form. Fig. H is e detail section taken on :1 line corresponding to line 2-2 of Fig. I, through the face pie 7 being shown in full lines.

the lenses. Fig. TV is a view of the face plate showing on lens openings and securing l l i is a sectional detail throng n the cast: showing one lens and a lamp. side elevation of a modified which the shank of the lens is provid complete screw threadinsteed of rhe shown in H.

in the drawings, similar reference characters re r similar parts throughout the several vievvs, and the sectional views are taken looking in the direction of the little srrows at the ends of the section lines.

Referring to the drawing, 1 is a sheet metal taco plate of a sign. The face plate is, in practice, the Wall of a casing, in 'WlilCli the illuminating lamps, as 2, are inclosed. As the structural details of the casing iorln no part of my present invention, ll do not illustrate or describe the same herein. A satisfactory casing structure is shown in the patent to Smith, No. 962,724, dated July 28th, 1910, and l preferably embody my iniproveinents in ii sign of the'charactcr taerc indicated.

The lenses 3 are arranged in the face plate in groups to form the sign indica or cherao ters, or to produce any suitable design or outline. The lenses 3 are preferably convex and provided With cylindrical shanks inner sides of the lenses being to provide shoulders 5. The ends of the pyramidal to provide a plural-i7 ref? ing surfaces The face plate prov with circular openings 7, of such die that the shanks are turning F1 The shanks are provided Whh t ribs 8, which are spaced from are stantially parallel with the should The ends of the ribs are spaced at 9, end deflected toward the end of the as at it).

The lug ll, which is formed 031 sheetmetal folded over the edge or ing, as shown, engages the rib 9 the lens in place, the lens acing t hring the lug; between the rib the der. This forms simple etlect' curing means for lens, one enables the lenses to he rapidly.

lln the modified stru the shank is nrovi crew thread 12, the sing spaced from e lug. By -nses es descrihed, *yremidal, a plural" s rovided, so that 0 ions in crises tive to th suhst A forth e1. hts ohvi one casino rel-a .nsrnit orrn amounts c l is For instance, is pieced suhstan lamp, as is shown W surfaces on the shank prevent; the ht shining directly through the len I is the case With lenses oi" the type commonly use that is, lenses having concave shanks. T his ohviates the necessity for the use of shields,

and the necessity of great care in the placing of the lamps relative to the lenses, and further, the lenses transmit a uniform amount of light, thus greatly adding to the appearance of the sign. Owing to the pyramidal form of the shank, care of the adjustment of the lens in the openings is not required, as there is no necessity for adjusting the lenses to bring the refracting surfaces into position relative to the lamp.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A sign comprising a face plate of sheet metal containing a substantially circular opening, a clip-like lug folded over the edge of the opening, and a lens provided with a shoulder arranged to contact with the side of the plate and with a shank having a thread-like lug engaging rib spaced from and parallel with the shoulder, there being a'space between the ends of the rib adapted to receive said lug, one end of the rib being curved toward the end of the shank.

2. A sign comprising a face plate of Sheet metal containing a substantially circular opening and provided with a lug projecting into the circle of said opening, and a lens provided with a shoulder arranged to contact with the side of the plate and with a shank having a thread-like rib spaced from and parallel with said shoulder, there being a space between the ends of the rib adapted to receive said lug, one end of the rib being deflected toward the end of the shank.

3. A sign comprising a face plate of sheet metal containing a substantially circular opening; a clip like lug folded from the edge of the opening; and a lens provided with a shoulder arranged to contact with my hand and seal in the presence of two wit nesses.
